Auto-restart VM from Linux Shell
by Andrei Verovski 12 Mar '18

12 Mar '18

Hi ! I have stubborn VM which time to time freezes, and watchdog for whatever reason don't restart it. Basically I would like to combine these 3 command into one script. ovirt-shell -l https://node00.mydomain.com.lv/ovirt-engine/api --ca-file="/etc/pki/ovirt-engine/ca.pem" -u "admin@internal" --password "secret" action vm MyVM stop action vm MyVM start Now I have problems. 1) Option --password "secret" is not recognized anymore in oVirt Shell 4.2. 2) What is the proper syntax to connect & run certain command in oVirt Shell 4.2? Something like: ovirt-shell -l https://node00.mydomain.com.lv/ovirt-engine/api --ca-file="/etc/pki/ovirt-engine/ca.pem" -u "admin@internal" --password "secret" && action vm MyVM stop Thanks in advance Andrei

Having trouble setting up Ovirt
by Kristian Petersen 12 Mar '18

12 Mar '18

I am trying to setup Ovirt with a self hosted engine and NFS storage for said engine. The storage appears to mounting OK, but when it gets to the point that it is initializing the lockspace it fails spectacularly and shows a Python traceback which I cleaned up and have included below: Traceback (most recent call last): File "/usr/lib64/python2.7/runpy.py", line 162, in _run_module_as_main "__main__", fname, loader, pkg_name) File "/usr/lib64/python2.7/runpy.py", line 72, in _run_code exec code in run_globals File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_setup/reinitialize_lockspace.py", line 30, in <module> ha_cli.reset_lockspace(force) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/client/client.py", line 270, in reset_lockspace stats = broker.get_stats_from_storage() File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/lib/brokerlink.py", line 135, in get_stats_from_storage result = self._proxy.get_stats() File "/usr/lib64/python2.7/xmlrpclib.py", line 1233, in __call__ return self.__send(self.__name, args) File "/usr/lib64/python2.7/xmlrpclib.py", line 1587, in __request verbose=self.__verbose File "/usr/lib64/python2.7/xmlrpclib.py", line 1273, in request return self.single_request(host, handler, request_body, verbose) File "/usr/lib64/python2.7/xmlrpclib.py", line 1301, in single_request self.send_content(h, request_body) File "/usr/lib64/python2.7/xmlrpclib.py", line 1448, in send_content connection.endheaders(request_body) File "/usr/lib64/python2.7/httplib.py", line 1013, in endheaders self._send_output(message_body) File "/usr/lib64/python2.7/httplib.py", line 864, in _send_output self.send(msg) File "/usr/lib64/python2.7/httplib.py", line 826, in send self.connect() File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/lib/unixrpc.py", line 52, in connect self.sock.connect(base64.b16decode(self.host)) File "/usr/lib64/python2.7/socket.py", line 224, in meth return getattr(self._sock,name)(*args) socket.error: [Errno 2] No such file or directory The messier ansible output is below: [ INFO ] TASK [Initialize lockspace volume] [ ERROR ] fatal: [localhost]: FAILED!

PostgreSQL tuning in oVirt
by Hari Prasanth Loganathan 12 Mar '18

12 Mar '18

Hi Team, We increased the number of threads in Apache web server and JBoss and we are able to scale up to 500 concurrent requests in oVirt. But after the long run, we are getting the below error from PostgreSQL but the oVirt is still running successfully. org.springframework.dao.DataAccessResourceFailureException: PreparedStatementCallback; SQL [select * from getvdcoptionbyname(?, ?)]; This connection has been closed.; nested exception is org.postgresql.util.PSQLException: This connection has been closed. 1) Could somebody explain this error? 2) What are the tuning parameters for PostgreSQL?

Failure to upgrade Cluster Compatibility Version
by Jonathan Mathews 12 Mar '18

12 Mar '18

I have been upgrading my oVirt platform from 3.4 and I am trying to get to 4.2. I have managed to get the platform to 3.6, but need to upgrade the Cluster Compatibility Version. When I select 3.6 in the Cluster Compatibility Version and select OK, it highlights Compatibility Version in red, (image attached). There are no errors been displayed on screen, or in the /var/log/ovirt-engine/engine.log file. Please let me know if I am missing something and how I can resolve this? Thanks Jonathan

Weekly fstrim & Ubuntu 16.04 LTS guest freeze
by Andrei Verovski 12 Mar '18

12 Mar '18

Hi ! I have stubborn VM (Ubuntu 16.04 LTS) which randomly freezes about each 2 - 3 weeks at weekends (when load is close to zero). No updates or kernel upgrades help. Freeze is not detected by oVirt watchdog and VM is not automatically restarted. Since it happens only on weekends, I suspect some weekly cron job may cause this. Ubuntu 16.04 LTS is installed on qcow2 disk image (thin provision). is it possible that fstrim (which discards / trims unused blocks) is a source of this problem ? Thanks in advance Andrei

4.2 upgrade question
by KSNull Zero 12 Mar '18

12 Mar '18

Hello! Currently we run 4.1.9 and try to upgrade to the latest 4.2 release. Our DB server is on separate machine and run PostgreSQL 9.2.23. During upgrade the following error occurs: [WARNING] This release requires PostgreSQL server 9.5.9 but the engine database is currently hosted on PostgreSQL server 9.2.23 [ ERROR ] Please upgrade the PostgreSQL instance that serves the engine database to 9.5.9 and retry. Ok, so we need to upgrade PostgreSQL. The question is - do we need to have exact 9.5.9 version of PostgreSQL ? Because if we upgrade PostgreSQL to the latest available 9.5.12 the same error occurs saying that client and server version mismatched and upgrade terminates. Thank you.

Hi, I found the messages at http://lists.ovirt.org/pipermail/users/2018-January/086631.html in your archive and am running into a similar/identical issue when trying to install a hosted engine: After providing all of the information, the installer does create some files on the nfs share (plantfiler02:/storage/vmx/ovirt) but eventually dies with: [ INFO ] TASK [Copy configuration files to the right location on host] [ INFO ] TASK [Copy configuration archive to storage] [ ERROR ] [WARNING]: Failure using method (v2_runner_on_failed) in callback plugin [ ERROR ] (<ansible.plugins.callback.1_otopi_json.CallbackModule object at 0x25c86d0>): [ ERROR ] 'ascii' codec can't encode character u'\u2018' in position 489: ordinal not in [ ERROR ] range(128) [ ERROR ] Failed to execute stage 'Closing up': Failed executing ansible-playbook [ INFO ] Stage: Clean up The relevant part in the logfile I believe is the following: 2018-03-09 09:05:05,762+0100 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:94 {u'_ansible_parsed': True, u'stderr_lines': [u'dd: failed to open \u2018/rhev/data-center/mnt/plantfiler02:_storage_vmx_ovirt/017fcf64-45c8-4289-87f7-c1195f7ec584/images/f36c079b-ba17-4c14-96a2-2b2beea7d989/56cd3448-4ecf-490e-99cc-ace36b977a9a\u2019: Permission denied'], u'cmd': [u'dd', u'bs=20480', u'count=1', u'oflag=direct', u'if=/var/tmp/localvmf0uaFh/56cd3448-4ecf-490e-99cc-ace36b977a9a', u'of=/rhev/data-center/mnt/plantfiler02:_storage_vmx_ovirt/017fcf64-45c8-4289-87f7-c1195f7ec584/images/f36c079b-ba17-4c14-96a2-2b2beea7d989/56cd3448-4ecf-490e-99cc-ace36b977a9a'], u'end': u'2018-03-09 09:05:05.565013', u'_ansible_no_log': False, u'stdout': u'', u'changed': True, u'start': u'2018-03-09 09:05:05.557703', u'delta': u'0:00:00.007310', u'stderr': u'dd: failed to open \u2018/rhev/data-center/mnt/plantfiler02:_storage_vmx_ovirt/017fcf64-45c8-4289-87f7-c1195f7ec584/images/f36c079b-ba17-4c14-96a2-2b2beea7d989/56cd3448-4ecf-490e-99cc-ace36b977a9a\u2019: Permission denied', u'rc': 1, u'invocation': {u'module_args': {u'warn': True, u'executable': None, u'_uses_shell': False, u'_raw_params': u'dd bs=20480 count=1 oflag=direct if="/var/tmp/localvmf0uaFh/56cd3448-4ecf-490e-99cc-ace36b977a9a" of="/rhev/data-center/mnt/plantfiler02:_storage_vmx_ovirt/017fcf64-45c8-4289-87f7-c1195f7ec584/images/f36c079b-ba17-4c14-96a2-2b2beea7d989/56cd3448-4ecf-490e-99cc-ace36b977a9a"', u'removes': None, u'creates': None, u'chdir': None, u'stdin': None}}, u'stdout_lines': [], u'ms I did create vdsm user and kvm user and group on the NFS server and I succesfully ran the nfs-check.py script from the host where ovirt should be installed: # python nfs-check.py plantfiler02:/storage/vmx/ovirt/ Current hostname: hyena.******.de - IP addr 10.216.60.21 Trying to /bin/mount -t nfs plantfiler02:/storage/vmx/ovirt/...

Am I missing the obvious somewhere regarding permissions? Is there a known solution/workaround to this?

We got an inactive FC storage domain that we cannot activate any more. We s= ee several events at that time starting with: VM perftest-c17 is down with error. Exit message: Unable to get volume size= for domain b83c159c-4ad6-4613-ba16-bab95ccd10c0 volume 686376c1-4be1-44c3-= 89a3-0a8addc8fdf2. Trying to activate the strorage domain results in the following alert event= for each host: VDSM <hostname> command GetVGInfoVDS failed: Volume Group does not exist: (= u'vg_uuid: 813oRe-64r8-mloU-k9G2-LFsS-dXSG-hpN4kf',) And after those messages from all hosts we get: VDSM command ActivateStorageDomainVDS failed: Storage domain does not exist= : (u'b83c159c-4ad6-4613-ba16-bab95ccd10c0',) Failed to activate Storage Domain VMHOST_LUN_205 (Data Center Production) b= y <user> Invalid status on Data Center Production.

Checking the hosts with multipath -ll we see the LUN without errors. We run oVirt 4.2.1 on CentOS 7.4. Hosts are CentOS 7.4 hosts with oVirt ins= talled using oVirt engine.
